Bowline never came loose on me even once in my life. Never heard of
such. Never read of such. Once tension is on them, takes a little
doing to get them loose.
Towertalk has the distinction of carrying the only mention of bowline
self-loosening I've seen in my entire lifetime. Maybe it doesn't
happen.
